Puzzle Style Acorn Locks 12mmx1.5 Thread
This set includes 4 pieces puzzle style acorn style 12mmx1.5 thread chromed wheel locks and 1 key. They fit many newer cars and trucks.
Fitment and specs
- Thread size: 12x1.5 (12 mm stud diameter, 1.5 mm thread pitch)
- Puzzle style locking pattern with 1 matching key included
- Acorn style seat, same taper as standard acorn lug nuts
- Chromed finish
- Set of 4 locks, one per wheel
- Fits many newer cars and trucks
Remove one lug nut per wheel and install a lock in its place using the included key. Torque to your vehicle's spec with a torque wrench, checking our torque reference chart if you need the number, then re-torque after 50 to 100 miles. Hand tools only on the key; an impact gun can chew up the puzzle pattern.
Common questions
Can I use these if my studs are 12x1.25?
No. Thread pitch has to match exactly. A 12x1.25 stud needs the 12x1.25 version of this lock; forcing the wrong pitch will damage the stud threads.
What do I do at tire rotations?
Hand the key to the shop before service. The locks come off and go back on like regular lug nuts once the key is seated, so keep the key in your glove box where you can find it.
